6 Best 3D Rendering Software 2021 (Some are Free!)

The best 3D rendering software is a crucial tool for professionals across a huge range of industries – architecture, film and VFX, video games, automotive design, fashion – the list goes on. It allows users to take user-created 3D models and bring them to life in fully-realized 3D environments or images.

Theres a wide variety of 3D rendering software solutions available, each being unique in their own way. So when it comes to choosing a 3D rendering software to use, you need to take a range of factors into consideration to make sure you pick the best one for you. 

Are you looking for software that offers CPU rendering, GPU rendering or both? What rendering features do you need? What material types do you need? What 3D modeling and CAD programs is the rendering software compatible with? These are just a few of the considerations you’ll need to make. 

Of course, youll also need to think about price. High-end commercial 3D rendering software can cost thousands of dollars, so its not accessible to everyone. Luckily, there are several high quality open-source software options that are completely free to use. 

In this guide, we reveal the best 3D rendering software available right now, covering both free and commercial solutions. Well take a look at the key aspects of each program to help you find the best 3D software for you. Before that, though, lets take a closer look at exactly how 3D rendering software works. 

What is 3D Rendering Software? 

3D rendering is the final step in the 3D animation process. It essentially involves the transformation of 3D models that can only be viewed in special software into fully realized images and videos can be viewed by anyone, for example, in the form of a movie on our TV, laptop or smartphone.

3D rendering software

3D rendering is used in conjunction with 3D modeling and CAD software. Once the models are complete, designers and developers insert objects and characters into graphically appropriate settings.

The best 3D model rendering software allows users to add effects like lighting, texturing and weather to bring environments to life, and 3D rendered images are usually interactive, navigable and scalable. 

3D Rendering Applications 

3D rendering is used across a wide variety of industries. The most recognizable use is in the entertainment industry, specifically in movies and video games. These days, virtually every film or video game that uses CGI or animation has used 3D rendering software in the production process. 

Another industry which makes major use of 3D rendering software is architecture. Some rendering software, such as Lumion, are specifically made for architects. While architects use CAD software to come up with initial designs, models and blueprints, 3D rendering software allows them to bring these designs to life in a format that’s easily shareable and understandable.

Architecture 3D rendering software

Another interesting use of 3D rendering software is in the healthcare industry. It can be used in the process of creating fully realized, 3D images of prosthetics, scanned body parts, tools, and implants that are easily accessible by different healthcare workers, potentially helping to increase the accuracy and efficiency of procedures. 

Other industries that use 3D rendering software include fashion, product design, interior design, automotive design, geology, manufacturing, construction, publishing and advertising.

  • Price: Free!
Luxcorerender

LuxCoreRender is another popular free 3D rendering software thats powerful, easy to use and packed with useful features 

This software offers physically based rendering, meaning that it’s built on physically based equations that model the transportation of light. This means the software fully supports high-dynamic range rendering and allows it to accurately capture a wide range of phenomena, such as subsurface scattering and volumetrics, producing photorealistic results. 

LuxCoreRender has a range of material types, from generic materials like matte and glossy to physically accurate representations of glass, metal and car paint. You can mix and modify all materials using textures. All materials also support bump and normal mapping. 

Some of the advanced features offered by LuxCoreRender include tone mapping and motion blur, depth of field and lens effects. It uses OpenCL to run on any number of CPUs and/or GPUs available, making for reduced rendering times due to the favorable performance of GPUs over CPU-only rendering. 

Another benefit of this software is that it supports dynamic and interactive scene editing, allowing you to pause and continue at any time. It even allows for the current state of renderings to be written to files so that you can continue rendering at a later date, either on the same computer or a different one.

Best Paid 3D Rendering Software 

Iray – Quality GPU Ray Tracing Renderer  

  • Price: From $295 per year 
Iray 3D rendering software

Developed by NVidia, Iray is a biased GPU renderer that’s one of the best 3D CAD rendering software aimed at beginners, students and hobbyists who don’t have expert rendering knowledge, as well as professionals. 

However, while it may be beginner-friendly, Iray’s quality shouldn’t be underestimated. This intuitive, physically based rendering technology uses AI denoising, CUDA, NVidia OptiX and Material Definition Language (MDL) to generate photorealistic imagery with great speed and efficiency, making it one of the most realistic 3D rendering software. 

To explain that in more detail, AI denoising is the use of Tenor Cores on the latest NVidia hardware to bring the power of deep learning to both final-frame and interactive photorealistic renderings. This speeds up the completion of final images and smoothes interactive rendering, producing a faster understanding of your scene’s composition and lighting. 

NVidia MDL defines the property of material, from surface colors to the light emission of surfaces. This also includes surface geometric properties that aren’t usually modeled in the geometric description of surfaces, including displacements, bump maps and cut-outs. 

Despite being a GPU renderer that’s developed for real-time usage scenarios, Iray also has many of the features typical of CPU solutions, including caustics, volumetrics, instancing and subsurface scattering. 

Iray is targeted at the architecture, engineering, construction, education, manufacturing and entertainment industries. It has been used in the design of several automotives and is one of the best 3D car rendering software, with the NVidia website covering some of the projects it has been involved in.
